We study the unipotent elements of disconnected algebraic groups of the form, whereis a simple algebraic group in characteristicpossessing a graph automorphismof order. We classify the unipotent classes in the cosetand determine the corresponding centralizers, showing that these bear a close relation to classes in a certain natural connected overgroup of. We also obtain a formula for the total number of outer unipotent elements in the finite group, whereis a Frobenius morphism, analogous to the well-known Steinberg formula for the number of inner unipotent elements.
